DIN EN ISO 2898-2-2009 塑料.增塑聚氯乙烯(PVC-P)模塑和挤塑材料.第2部分:试样制备和性能测定
Plastics - Plasticized poly(vinyl chloride) (PVC-P) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties (ISO 2898-2:2008); English version of DIN EN ISO 2898-2:2009-03
This part of ISO 2898 specifies the methods of preparation of test specimens and the test methods to be used
in determining the properties of PVC-P moulding and extrusion materials. Requirements for handling test
material and for conditioning both the test material before moulding and the specimens before testing are given.
Procedures and conditions for the preparation of test specimens and procedures for measuring properties of
the materials from which these specimens are made are given. Properties and test methods which are suitable
and necessary to characterize PVC-P moulding and extrusion materials are listed.
The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide
use for, or of particular significance to, these moulding and extrusion materials are also included in this part of
ISO 2898, as are the designatory properties specified in ISO 2898-1.
In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation
and conditioning, the specimen dimensions and the test procedures specified herein. Values determined will
not necessarily be identical to those obtained using specimens of different dimensions or prepared using
different procedures.
